摘要
将汽车电动助力转向系统(EPS)模型、转向模型和主动悬架系统(ASS)模型相结合,建立了整车系统的动力学模型。设计了输出反馈随机次优控制策略,实现了汽车EPS和ASS的集成控制。在Matlab/Simulink环境下进行了仿真计算,仿真结果表明,采用所提出的集成控制策略,不仅能有效改善EPS的轻便性,而且使得ASS具有很好衰减路面振动、抗侧倾和抗俯仰的能力,从而显著提高了汽车操纵稳定性、安全性和平顺性等综合性能。
Combining automotive Electrical Power Steering System(EPS) model and steering model with Active Suspension System(ASS), the paper set up a full car dynamic model. Based on the integrated model, the Random Sub-Optimal Control of output feedback was presented to implement integrated control of EPS and ASS. Under Matlab/Simulink, the simulation was done and the results show that the presented control scheme can improve handiness, and can reduce the road shocks and has a good anti-roll and anti-pitch ability, thereby improves vehicle maneuverability, safety and ride performance, and so on.
